This one doesn't quite click. It's a drive your wealthy wife crazy so you can inherit the money plot. And they let on right away that it's the husband. So, instead of "is she really crazy?", we have to ask "how can he be stopped?".
Since this is Hollywood, you know he will be stopped and also they give away who will stop him. So, there's not much suspense
left.

Movie #2080: Together (2000, Lukus Moodysson)

At first, this one looked familiar. Then, I realized I had seen it before but I kept watching anyway.
The story concerns a great number of people who are all screwed up. The kids not so much but the adults are definitely idiots. It's all very sad because you know that living with these idiots will surely cause the children to grow up just as warped.
Then there's the ending.
